(54) Variable-nozzle assembly for a turbocharger


(57) A variable-nozzle assembly (100) comprises a nozzle ring (110) and an array of vanes (120) circumferentially spaced about the nozzle ring (110) and rotatably mounted to the nozzle ring (110) such that the vanes are variable in setting angle, and an insert (130) having a tubular portion (132) and an annular nozzle portion (134) extending generally radially out from one end of the tubular portion. A plurality of axially extending holes extend through a thickness of the nozzle portion (134). A plurality of spacers (140) have first ends joined to the nozzle ring (110), opposite second ends of the spacers (140) being engaged in the holes (112,142) and secured to the nozzle portion (134) by welds formed at the second surface (138). An annular groove (250) is defined in the second surface (238) of the nozzle portion (234) radially inward of and proximate to the holes (242). Alternatively or additionally, discrete recesses (260) are formed in the second surface (238) adjacent the holes (242). The groove (250) and/or recesses (260) facilitate weld penetration.
